Mainly Win 7. Otherwise Mac OS X. Sometimes Win XP, and very rarely Ubuntu. But I almost never have a terminal open (and don't have a shortcut for that either) whereas Firefox almost always is. So I'm just 1 click away rather than 4 characters away. You taught me something though (I highly prefer typing on a keyboard than using a mouse or, worse, a touchpad) and I wish I had to spend more time in a terminal.

Why not? I usually have a terminal open for irc / bc -l / git / checking the headers of pages with curl -I, pinging things, WHOIS lookups, wgetting files, etc etc etc.

Because he's mainly in Windows? I avoid the command prompt like the devil there too.

Time.gov is slow and ugly and doesn't work on my phone. Fuck time.gov.

Have you tried the naval observatory master clock at http://tycho.usno.navy.mil/simpletime.html ?

Nice find. Thanks.

Very nice!

My little Ubuntu machine is -0.018 seconds (±0.009 seconds).

My MBP is -0.012 seconds (±0.021 seconds).

I recommend you add a percentile score of exactness, along with breakdowns based on platform, and suggestions about what to do if the percentile is disappointing.

Simple and amazing.

I used a simple shell script to query timezone info to find world time in CLI https://gist.github.com/2020097

I would still prefer to have the option to select the timezone. Sometimes I want to attend some workshops that announce the time in one of the US timezones and its always difficult to do the conversion.

That would be, as someone else mentioned in this thread, worldtimebuddy. I use it for exactly that purpose and consider it gorgeous.

The idea is you can scan it with your phone and not have to type the URL in. Not sure how many people actually do that though.

A) If you're viewing on your phone, it's mobile optimized B) If you're viewing it on your desktop, why would you want to go to your phone? C) Time.is has to be the easiest URL to enter by hand in a device browser. :D

I'm not saying it's very useful, but if you see it on your desktop and want to check it or save it on your phone (to verify the time on your phone/QR-and-web-enabled mobile device, to bookmark it for future reference when on the go, etc), the code might help. I've seen this used better than just on an 'about' page, though.

Any idea what geolocation method they're using here? It got my city spot-on when usual IP geolocators put me elsewhere.

NIST recently published the new ntp.leap file and it looks like we will have one this July... 3550089600 35 # 1 Jul 2012 [1]

You also need to make sure your IANA tzdata is updated to account for this. I think this leap second was first added in tzdata2012a, but I'd have to check: ftp://ftp.iana.org/tz/data/leapseconds

If you use Unix time, you don't have to care:

http://en.wikipedia.org/wiki/Unix_time

"Unix time, (...) is (...) defined as the number of seconds elapsed since midnight Coordinated Universal Time (UTC) of Thursday, January 1, 1970 (...) not counting leap seconds"

Not sure why Android does not have ntp built in. My network does not broadcast a time signal, maybe it is just assumed they all do.

Your cell network or you do not have multicast ntp enabled?

Cell network doesnt broadcast time. You can install ntp client, but it needs to run as root, and I wont let anything from the market run as root, and I havent got around to building an ntp client myself...

I like Time.gov, personally; it was the first site I ever found around this concept and so it has a soft spot. I keep finding all my physical atomic clock synced clocks (yes, I have more than one, they are cheap these days) disagreeing, sometimes by 2 seconds or more, which makes me laugh (great ideas ruined by poor implementation). I find many of the web sites (listed in comments or the original post) to also differ…

When I was a kid, my dad would always set our clocks by tuning the radio to one of the atomic clock broadcasts from Fort Collins. This might be the same source as your automatically synchronized clocks, but the advantage is that it's human-listenable, and not going through any computer networks or algorithms between Colorado and you. https://en.wikipedia.org/wiki/Radio_clock#List_of_radio_time...

Same here. My Dad is a life-long ham radio operator and if I hear a WWV broadcast now, it takes me back to my childhood in a flash.

On a related note, I always liked the British time announcements that used three tones, with the designated time being "at the third stroke". It's like a music conductor conducting a measure before you start playing or singing. I wonder if it's measurably more accurate than just playing a tone with the proper time is reached.
